HAYSTACKER.

Application filed August 28, 1922. Serial No. 584,820.

T all whom it may concern.

Be it known that I, WILLIAM Canon HUD- soN, residing at Keating, county of Baker, State of Oregon, citizen of the United States, have invented certain new and useful Improvements in Haystackers, of which the following is a specification.

The object of my invention is to provide a novel hay-stacker, with improved means for adjusting the swing of the load to the height desired, according to the increasing height of the stack; means for tripping the hay-fork to drop the load; and means for guiding the horizontal swing of the fork supporting-frame.

The invention is graphically disclosed in its preferred form in the accompanying drawings, forming part of this specification, like reference characters designating corresponding parts throughout the several views. Briefly described:

, Figure 1 is a view in side elevation of my hay-stacker.

Figure 2 is a top plan View thereof; Figure 3 is a horizontal section on the line 3-3, Fig. 1, looking in the direction indicated by the arrows thereon t Figure 4 is a fragmentary view in elevation,,partly in section, of thehay-stackerr Figure 5 is a view in perspective of the hay-stacker, parts being broken away.

Referring, now, in detail to the drawings: p

1, 1 designates base-members, and 2, 2 transverse base-members secured thereto, as shown at 3. 4 designates an intermediate transverse base-member, likewise secured, at its ends, to the base-member, 1. 5 designates a mast ro-tatably supported upon the base-member 4. f

Bars 6, 6 rise, convergently from one of the base-members 1, and are secured, at their upper ends, to an angleplate, comprising the flanges 7 and 8,,to which latter flange the bars 6, 6 are secured, as shownat 9. Apivot-pin 10 passesthrough the flange 7 and loosely into the top of the mast 5.

Bars 11,.11 rise convergently from the V other base-member 1, and may be secured, at their upper ends, as shown at 12, to a slat 13 extendingtransversely of and secured at its endsto the bars 6, 6. p

1'7. Preferably, the tongues19, 19 and 20, 20 are integral with the track, as shown,

so that it ispossible to stamp thetrack with its tongues out of a singlepiece of sheet metal. i

Rigidly secured to thelower end of'the mast 5, as by means of a pair of parallel, spaced plates 22, 22, is a bar 23:, for a pur pose. presently appearing. 5

Pivotally secured to the mast 5, as by means of the pivot pin 24:, is the supporting carriage ofthe lifting fork of the hay stack: er; The supporting carriage while it may be of any preferred form, is herein shown as comprising bars 25, 25, and transverse slats 26, 26'. As shown, the pivot pin 24 passes through said bars 25, 25, toward one end thereof.

The fork is of the conventional form and, comprises, as usual, a series of'spaced'parallel teeth 27. The fork is pivotally secured to the bars 25, 25 in any suitable manner, preferably by means of straps 28, 28 securedto one end of'the bars 25', 25, and provided, at their free extremities, withfeyes 29,29, passing through which are staples BOcarried' by a transverse slat 31 secured to the fork teeth 27, toward one endthereofj The lifting mechanism for the fork will now be described: v

Pivotally journaled in the bars .25, 25, toward the end thereof to which the fork is secured, is a rod 32.

One endof a cable 34: is secured to the pulley 33, the cablepassing over apull'eyr3'5, carried at the upperend ofcomplemen-tal arms 36 36, secured atone end tothe mast; 5 by bolts 37, and over the pulley ,33, thenceover a pulley 35' carried betweenthe arms 36, 36, thence through an opening-38" in the mast 5, and over a pulley 38in said opening, thence downward over a f 1 1 9 carried between the plates 22, 22 [and thence bare -e Pul eys 40? t earned a the free end of the arm 23. Thus, the operatorfby pulling upon the end of the cable 3a which projects between the pulleys 4:0, 40, will exert an upward pull on the rod 32, thereby raising the supporting carriage 25, on its pivot 24, the carriage carrying with it the fork. During the initial pull of such lifting movement, the carriage 25, 25 and the fork rise vertically without any side wise swinging movement, by reason of the fact that the upper portions of the cam track 18 are in a vertical plane, such vertical portions of the cam track extending from the tip a to the point 6. From the point I) the track isbent sidewise, as is shown by the shading thereon in Fig. 1. As the roller 41 reaches the lower end of the vertical portion of the track 18, it passes along the bent portion of the track, permitting the mast 5 to he swung around, swinging around with i the carriage 25, 25 and the fork carried thereby.

The roller 11 issecured on one end of a bifurcated member d2, the furcations 48 of fsimilar opening 57 in the mast ,5, thence which are pivotally secured at the ends thereof, as shown at 44:, to the mast 5. Between the furcations 43, 43 of the member 42 is projected an arm 45 pivotally secured at its upper end, as shown at 46, to one end of the carriage beams 25, 25. The other end of said lifting arm 45 18 provided with a longitudinally extending series of openings 47,

through any one of which, and through aligned openings 48 in the furcations 43, 4:3, a pin 49 may pass. By this means the liftingarm 45 is adjusta'bly secured to the member 42. In this manner, also, the lateral swinging of the rod on the fork may be ad- 'justed to the height desired, according to the increased height of the stack.

It should'be understood that the mast 5 is rotatable in one direction only; because one of the arms 36, rigid with the mast, contacts with the adjacent upright frame bar 6, as will be understood by reference to Fig. 5, so that rotary movement of the mastin a direction to move the roller 41 away from the cam track'18 is prevented.

Theinvention comprehends suitable tripping means for the fork, whereby the same may be released atthe proper time, so as to dumpthe load. :The preferred form of such mechanism is shown in the drawings and.

will now be described:

7 "Secured-to an eye 50, carried intermediate of the length of a transversebar 51 of the fork, is a cable 52 passing over a guide-pulley 53 carried bythe slat 26, and thence upward over a similar pulley 54: carried in an opening '55 in the mast 5, thence downward over a third pulley56, likewise carried in a through said opening 57 downwardto an eyein the upper end of the segment 58 pivotally secured, as shown at 59, to a bracket 60 of the segment.

secured, as at 61, to the mast 5. The segited swing thereof than is afforded by the lu s 62 62 and in this instance I have shown the segment as provided with a serie of openings 63, through any one of which a pin (not shown) may pass, as is obvious,

such pinfunctioning as does the lower stop 62, to contact with. the bracket 60 in the upward movement of the segment, thereby limiting the upward swing thereof. The segment 58 is provided with a notch 64: normally engaged by the beak 65 of a tripper 66 pivotally secured, as shown at 67, to the bracket 60.

In operation, after the load has been lifted on the fork of the hay stacker and the mast 5 has been swung around with the carriage 25, 25, so as properly to position the fork over the stack, the operator pulls upward upon the tripper 66, thus releasing the'beak 65 thereon, from the notch 64, whereupon the weight of the load upon the fork immediately tilts the fork downward, thus pulling upon the cable 52 and oscillating the segment 58 upward on its pivot 59, the swinging movement of the segment and, consequently, the degree of drop or tilting movement of the fork, being governed by the lower stop 62, which contacts with the bracket 60. i

It may be explained that the lower stop 62 is so positioned on the segment 58 as to permit the fork to swing downward, from s position with reference to the ground, thus.

permitting the load to slide off of the fork at the desired angle. In other words, by the construction described, the load raised on the fork may be dropped straight down or may be permitted to slide off it at an angle.

Suitable means are provided for automatically returning the fork and segment 58 to normal position, after dropping of the load from the fork, as just described, and, in this instance, such means comprises a coiled spring 68 secured atone end'to the segment and at its other end to an eye 65 carried by the mast 5. V r

i It will thus be seen that my invention comprehends a hay stacker of novel construction, embodying novel instrumentalities for permitting an initial vertical lifting of the fork and a subsequent bodily swinging movement thereof in a horizontal plane; and novel instrumentalities for permitting the fork to drop either vertically or to an inclined position; and, finally, novel instrumentalities for adjusting the lateral swinging of the load to the height desired according to the increased height of the stack.

What I claim to be new and desire to secure by Letters Patent is:

1. In a hay stacker, the combination with a vertical revoluble mast, of a substantially U-shaped strip of metal, constituting a cam track, fixed relative to the mast, an arm pivotally secured to said mast and carrying a roller moving on said cam-track, a hay-fork supporting carriage pivotally secured to said mast, and a connection between said supporting carriage and said arm.

2. In a hay stacker, the combination with a vertical revoluble mast, of a substantially U-shaped strip of metal, constituting a camtrack, fixed relative to the mast, an'arm pivotally secured to said mast and carrying a roller moving on said cam-track, a hay-fork supporting carriage pivotally secured to said mast, and a connection between said supporting carriage and said arm and adjustably secured to'the latter.

3. In a hay-stacker, the combination with a vertical revoluble mast, of a substantially U-shaped strip of metal, constituting a camtrack, fixed relative to said mast, an arm pivotally secured to said mast and carrying a roller moving on said cam-track, a hayfork supporting carriage pivotally secured to said mast, a hay fork pivotally secured to trip member one end of said carriage, and means for tripping said hay fork to permit the same to drop under the weight of the load thereon.

4. In a hay stacker, the combination with a vertical revoluble mast, of a substantially U-shaped strip of metal, constituting a camtrack, fixed relative to the mast, an arm pivotally secured to said mast and carrying a roller moving on said cam-track, a hayfork supporting carriage pivotally secured to said mast, and means for tripping said hay fork to permit the same to drop under the Weight of the load thereon, said tripping means comprising a pivoted segment and a normally engaging the segment.

5. In a hay stacker, the combination with a vertical revoluble mast, of a substantially U-shaped strip of metal, constituting a camtrack, fixed relative to the mast, a hay-fork supporting carriage pivotally secured to said mast, a hay fork pivotally secured to one end of said supporting carriage, and means for tripping said hay fork to permit the same to drop under theweight of the load thereon, said tripping means comprising a pivoted segment and a trip member normally engaging the segment, said segment being carried by a bracket and provided with a series of openings, and a pin engageable with any one of said openings and contacting with said bracket to limit upward move-f ment of said segment.

In testimony whereof I hereunto afiix my signature.
